Me: It's me again, self. WTF? She wants to be independent, let her be independent. Draw a line. Don't let yourself be treated disrespectfully. Let her see what "independence" is really like. Have fun moving the couch upstairs with your feaking GF. I will not condone this. She will not get my blessing.
Definitely go with Me#2. Do not help her. You have been very understanding and empathetic - and where has it gotten you? Her moving out? Let her feel her "independence"/ lonliness.
